wl12xx: report the stop_ba event to all STAs in AP-mode
Use the AP_MAX_LINKS as the upper boundary for traversing the links array,
thereby guaranteeing BA sessions with all connected STAs are stopped when
the stop_ba event is received.
On roaming, the auth and assoc req are sent with the sta
hlid. This is wrong, as the sta hlid is configured according
to the old ap. Use the dev_hlid instead.
Move the wl1271_tx_update_filters() call into wl1271_tx_get_hlid(),
so wl->dev_hlid will be valid.
wl12xx: send all pending packets on channel change
There is a race condition between wl1271_tx_work() and the
channel switch, so make sure all the pending packets are
being sent before switching channel.
wl12xx uses a single probe response template, regardless of
the probe request.
However, the P2P spec forbids including the p2p ie in some
cases (e.g. the probe request didn't include the p2p ie).
The fw responds only to probe requests that don't
include the p2p ie, and passes up probe requests that
include them (the supplicant will answer them).
Thus, strip the p2p ie from the probe response template.
